发明名称 METHOD AND APPARATUS FOR CONTROLLING MEMORY STORAGE LOCKS BASED ON CACHE LINE OWNERSHIP
摘要 A system and method for controlling storage locks based on cache line ownership. Ownership of target data segments (cache lines) is acquired at a memory (MSU, TLC, SC) targeted by a first requesting device (400, 402). A storage lock is enabled (306) that prohibits requesting devices, other than the first requesting device, from acting on the target data segments during the time the targeted memory possesses ownership of the target data segments. A storage lock release signal is issued from the first requesting device to the targeted memory when exclusivity of the target data segments is no longer required at the first requesting device. In response, the storage lock at the targeted memory is released (414), thereby allowing (416) other requesting devices to act on the target data segments.
